Stay away from Turbo 10, they are the same. I would try Enhance, 7Search and LookSmart. Be sure to contact them first and get a rep, then ask them to turn on whatever filters you want (yes, you have to ask), then get some good tracking software like DirectTrack. You'll need it to monitor Click Fraud.
You could also use the PPC companies tracking code but that means installing code from each one into your "thank you for your purchase" pages, and some of it isn't so good. Plus this only tracks conversions. (Except LookSmart. They have Click Fraud tracking, although its still code you have to install in the same page as your conversion tracking.
Good Luck,
